The engine does not start after winter storage. No spark at any cylinder. The engine cracks and the battery is new and full!
Kill switch tested! Remote at neutral e.t.c
The story is that the engine could not start with no spark after winter storage. One day I tried again and it started and run for 15 minutes.
After that day it does the same. It does not start with no spark in any cylinder.
Any Help will be appreciated!

Tech told me that may be the problem is in the optical sensor or in the power unit.

PLEASE HELP

Engine is 1999 model BJ90PLEEB
